Abstract
The utility model discloses a force measuring device including a dynamometer and an indicator. A first mini-type single-chip microprocessor of the dynamometer connects with a first wireless sending and receiving device and sends measurement data through the first wireless sending and receiving device. And the first wireless sending and receiving device are in a full-duplex communication. Control instructions from the indicator can be received for parameter setting, calibrating and function controlling of the dynamometer at the same time of sending the data. A second mini-type single-chip microprocessor of the dynamometer receives the measurement data through a second wireless sending and receiving device and displays the measurement data through a display. The second wireless sending and receiving device is also in a full-duplex communication. Instructions can be sent to the dynamometer and relevant parameters of the dynamometer can be set at the same time of receiving the data of the dynamometer. In the prior art, multi-core cable connection is adopted in a dynamometer, thereby causing an inaccurate measurement result easily. When the dynamometer in the prior art is used in a dangerous condition, the dynamometer probably brings harm to a tester. The force measuring device in the utility model overcomes the above technical defect and can be used conveniently.
